56 holder 1. This punch 9 is provided on one side Having thus described my invention what I claim as new and desire to secure by Letters Patcut is:

1. A device of the class described comprising a tool holder having an opening formed therein for the reception of a tool; a latch member slidably mounted on said holder and projectible, at one end, into said opening; resilient means for normally maintaining said member projected into said opening, said latch member having a beveled surface adjacent its forward end; an actuating member slidably mounted on said holder and movable axially of said opening and engaging said surface for effecting a retracting of said latch member; and a curvilinear member engageable with said actuating member, prior to engagement of the same with the said beveled surface, for effecting a partial retraction of said latch memher.

2. A device of the class described comprising a tool holder having a tool receiving opening formed therein; a latch member slidably mounted on said holder; a portion on said member adapted, upon movement of said latch member into a predetermined position, for projecting into said opening, said portion having a slot formed therein intermediate its ends; a spring for normally moving said member into said pre-determined position and tending to resist its retraction therefrom, the forward side of said member, at the rear of said slot, having an inclined surface; a roller positioned below and engageable with said member; a retracting member having a tapered portion at its upper end and slidable of said holder axially of said opening and engageable on an inclined surface with said roller for forcing said member rearwardly and, subsequently to a movement of said member, for engaging said inclined surface and effecting a withdrawal of said portion from said opening.
